CRUDE-OIL BURNER.

Application filed October 22 To all 'whom t may concern Be it known that I, JOHN VVEsTALL, a citililassachusetts, have invented certain new and useful Improvements 'in Grudc- Oil Burners, of which the following is a specification, yreference being had to the accompanying drawings.

l `l1is invention relates to an improved crude oil burner, and has for its primary object to provide a burner of-this character primarily designed for use in connection with heating furnaces ot' either the hot air or hot water type, whereby the furnace may be economically operated.

It is a more particular object ot the invention to provide a crude oil burner having simple. and improved means for breaking up the partly vapor-ized oil and thoroughly mixing the saine with air. whereby complete combustion will be obtained.

It is likewise another important object ot the invention to provide an improved burner plate construction and a perforated oil supply coil, said burner plate being provided with a plurality of air openings, and a rotary gas breaker mounted and arranged with relation to the coil and the burner plate so as to create a forced dratt'ot' air through the burner plate and the mixture of the same with the partially vaporized oil.

And it is a further general object of the invention to provide a iuel oil burner as above characterized, which is simply and dui-ably constructed, may be readily mounted in operative position within a furnace Without requiring structural alterations in the latter, and which may also be manufactured and sold at comparatively small cost.

With the above and other objects in view, the invention consists in the improved construct-ion, combination and relative arrangement of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawings in which similar reference characters designate corresponding parts throughout the several views. and wherein Figure 1 is a side elevation illustrating the preferred embodiment otl the invention;

Referring in detail to the drawings, designates the Ibase plate, which preferably :t`orrned with an upstanding annular flange (3, andcentrally provided with a hollow boss 7 to receive a bushing` 8.

A second plate 9 is arranged above and in spaced relation to the base plate, and is likewise formed with an annular, opstanding ilange 10. lThe tlange ot' this plate is fixed to a plurality of vertically disposed supporting bars l1 which at their lower ends are integrally Jformed with, or suitably secured to= the liange G ol the base plate. The bars l1 extend for a considerable distance above the plate 9 and in their upper portions are provided with spaced openings 12. The body ot the plate S) is concave and inclines downwardly and inwardly from the niarginal tiange 10 to a central bearing boss 13 formed on said plate.

The burner casting llrl which is of cylindrical torni. is adapted to be arranged be tween the. upper ends ot the vertical bars l1 and secured thereto by the bolts7 shown at 15, which are engaged through the corresponding openings 12 in said bars in accordance with the desired height or elevation of the burner casting above the base plate.

1G designates the burner plate proper, which is corrugated to provide alternate ribs and grooves, and each of the ribs has a slot or opening 17 in the apex thereof. The eorrug-ations do not extend across the entire diameter ot' the burner plate, which is provided with a plane. tlat portion adjacent the annular body wall of the burner casting. llpon this flat portion ot the burner plate, a single pipe coil 1S tor the fuel oil is ar ranged and at one of its ends is provided with an elbow connection 19 extending radially through the wall of the burner casting. 'lhc other end ot' the pipe coil closed. This coil is provided with a. plurality oi spaced orifices Q0. through which the fuel oit is discharged upon the corrugated burner plate.

A vertically disposed shaft 21 is mounted titl at its lower end in a suitable step bearing formed in the bushing 8 which extends npwardly through the bearing 13 on the plate 9 and also through a central opening in the burner plate 1li. rlhe upper face of the bearing 13 is forined with a raceway for the bearing balls, indicated'at and a collar 23 fixed upon the shaft 2l is also provided with a similar raceway to receive the bearing balls. The shaft 2l is preferably hollow and to the same a belt pulley 2t is fixed. Around this pulley, a belt driven from a motor or other suitable source of power is adapted to be engaged.

Upon the upper end of the shaft 2l, and above the burner plate, the gas breaker or mixer fixed. This breaker consists of a plurality of radially disposed arms or blades which are integrally connected by the central hub or sleeve 26, in which the upper end of the shaft'lis engaged.. This shaft is preferably hollow in order that it may be driven to rotate the gas breaker with a minimum egqienditure of power. The arms .25 of the gas breaker are sufiiciently long to extend outwardly to a position inmediately above the'coil 18.

1n the event that the burner plate should he flooded with oil, the oil will flow downwardly through the openings 1T and drop upon the plate 9. As this plate is concave, the oil is directed inwardly toward the cen-A ter thereof and is recovered and used, in the manner to be presently explained.

rl`hc oil supply pipe, shown at 27, which extends from the supply tank or reservoir is connected to the elbow l), said pipe having a needle valve, indicated at 28, interposed therein, whereby the supply of fuel'oil to the coil 18 may be varied or regulated. suitable pump actuated from the motor which operates the gas breaker may be employcd for forcibly feeding the oil through the pipe 2T to the coil l'. 2) designates a second pipe leading from the supply source to a pilot light ill), disposed closely adjacent to the perforated side of the coil 1S. A valve 3l also arranged `in the pipe 2H. l2 designates a drain pipe leading from thc plate J at a point adjacent its center in a downward direction to the overflow pipe which returnsl the oil from the pilot light to the supply tank. The oil for the pilot light is preferably supplied lroin an auxiliary tank or reservoir by gravity. The pipe 32:3, however, leads from the burner to the main source of fuel supply. ill ind` ,at'es an automatically controlled cut-olf valve in the fuel supply pipe 27, which is preferably actuated by a suitable thermostat. This therniostat, however, constitutes no part partl ofmy invention and will not, therefore, be described in detail. lt will, however, be understood that in case of failure of proper operation of the thern'iostatieally controlled 1,293 ,aseo

valve after the burner flame is extinguished, the excess oil will be be drained by the over flow pipe 33 from the burner plate back to the main supply reservoir.

In the operation of my improved burner, when the motor is started, oil first issuing from the coil 1S upon the burner plate is ignited by the pilot light 30 and the oil flowing through the coil 18 becomes quickly heated to a very high deeree and partially vaporized. In the operation of the inctor, it will be understood that the oil breaker and mixer 25 is rotated at very high speed, and in the rotation thereof, air is drawn up through the openings 1T in the corrugated burner plate. The oil gas is thoroughly broken up by the rotating blades or arms of the breaker and 'mixed with the air so that complete combustion of the hydrocarbon gas is assured. Thus, kerosene and other relatively crude hydrocarbon oils may be utilized by means of the present invention for the heating of hot air or hot water furnaces. In the application of the burner to such use, the thermostatic means referred to for the control of the oil supply valve 34 may also control the operation of. the switch lever for the motor actuating the rotary gas breaker. Thus, in the event that the burner flame should be accidentally extinguished, the thermostat will operate to cut oli' further supply of oil and open the motor switch. As above stated, however, vin the event of .failure of proper operation of the ther1no static means, the overflow pipe, 33 will conduct the oil accumulating upon the burner plate back to the supply reservoir. The pilot light consuming any gas which may remain after the burner flame is extinguished. will prevent explosion which might otherwise oci eur from the accumulation of the gas. lVhilc l have referred to the invention principally designedf'for use in connection with heatingr furnaces, it is, ofcourse, manifest that thel device can also be :ulvantageously employed for various other purposes. The several parts ot' the improved burner are all of relatively simple form and can be manufactured at small cost and easily and quickly assembled in their proper operative positions. rl`he burner can be constructed in many different sizes in accordance with the purpose or use for which the same may be desired. The various elements above referred to are likewise susceptible of many modiications in their form, proportion a nd arrangement, and it is accordingly to be understood that l reserve the privilege of adopting all such legitimate changes as may be fairly ein bodied within the spirit and scope of the invention as claimed.
